    Nonlinear Crossflow Disturbances and Secondary Instabilities in Swept-Wing Boundary Layers

    We numerically solve the governing partial differential equations to study nonlinear evolution of crossflow disturbances in incompressible as well as compressible boundary layers. When the amplitude of these d...

    Oblique Mode Breakdown in a Supersonic Boundary Layer Using Nonlinear PSE

    Nonlinear, compressible parabolized stability equations (PSE) are used to study the transition process in a Mach 1.6 flat plate boundary layer. It is shown that two oblique first-mode waves interacting among t...

    Nonparallel Stability of Rotating Disk Flow Using PSE

    We use linear, parabolized stability equations (PSE) to study nonparallel stability of rotating disk flow. We find the nonparallel effect to be small when compared to the quasi-parallel theory of Malik, Wilkin...

    Discrete Modes and Continuous Spectra in a Mach 2 Boundary Layer

    The disturbance field (discrete modes and continuous spectra) induced due to a harmonic point source in a Mach 2 boundary layer is studied by using generalized Fourier transform techniques. The results show th...

    Transition Research in Low-Disturbance High-Speed Wind Tunnels

    The technical requirements and test data from the Mach 3.5 Pilot Low-Disturbance Tunnel are presented. This unique facility provides a test region with essentially zero-acoustic noise and simulates, for the fi...

    Effect of Wall Suction and Cooling on the Second Mode Instability

    Compressible linear viscous stability theory is used to study the effect of combined wall suction and cooling on the second mode instability in a flat plate boundary layer. While wall cooling destabilizes the ...

    Transition Prediction in External Flows via Linear Stability Theory

    Paper summarizes progress in relating linear stability theory to transition location. Linear stability theory computations for both flight and low-disturbance wind tunnels, at low and high speeds, and for T-S,...

    Effects of Nozzle Design Parameters on the Extent of Quiet Test Flow at Mach 3.5

    To advance boundary-layer stability and transition research and to ultimately provide reliable predictions of transition for supersonic flight vehicles, a wind tunnel is required with much lower stream disturb...

    Effect of Curvature on Cross-Flow Instability

    The problem of the stability of a three-dimensional laminar boundary layer formed on a curved surface is considered. A calculation scheme, which takes account of the curvature of the flow streamlines and of th...
